Berkeley FAQ
What if I want a no-mow native meadow?
Berkeley allows native bunchgrass landscapes if submitted as a fire-wise plan to the Vegetation Management Unit. Plants must be spaced and irrigated to prevent continuous fuel load.
Does this apply to vacant lots I own?
Yes. Vacant parcels are inspected and abated identically to occupied homes. Absentee owners are billed at the same rates and can face liens.
Sunol FAQ
When is the weed abatement deadline?
Annual deadlines are typically in late May or early June; check your annual notice from the Alameda County Fire Department Weed Abatement Program.
Can I request an extension?
Extensions are sometimes granted for weather or hardship; contact the fire department weed abatement coordinator before the deadline.
